When implementing a security framework to address these challenges, the CSO is faced with a buy vs. build option. They could engage developers to put together open source components to build Cloud Service Broker-like functionality from scratch. This approach creates the runtime components of a broker, such as routing to a particular Cloud Service Provider. However, other components of the solution, such as reporting and an audit trail, may not be present. An off-the-shelf Cloud Service Broker product will provide these extra features as standard and should also provide support for all the relevant WS-Security standards at a minimum.
As the Cloud Security Alliance notes in its Security Guidance White Paper. "Cloud Computing isn't necessarily more or less secure than your current environment. As with any new technology, it creates new risks and new opportunities. In some cases moving to the cloud provides an opportunity to re-architect older applications and infrastructure to meet or exceed modern security requirements. At other times the risk of moving sensitive data and applications to an emerging infrastructure might exceed your tolerance." I hope this article provides sufficient data points to guide readers on their journey.
